The radial distribution of radio emission from SN1993J: Magnetic field amplification due to the Rayleigh-Taylor instability

I. Marti-Vidal, C-I. Bjornsson, M. A. Perez-Torres +2

[SHORTENED VERSION] Observations of radio emission from young core-collapse supernovae (CCSNe) allow one to study the history of the pre-supernova stellar wind, trace the density s…

The 30-Year Search for the Compact Object in SN 1987A

Dennis Alp, Josefin Larsson, Claes Fransson +32

Despite more than 30 years of searches, the compact object in Supernova (SN) 1987A has not yet been detected. We present new limits on the compact object in SN 1987A using millimet…

Core-collapse and Type Ia supernovae with the SKA

M. A. Pérez-Torres, A. Alberdi, R. J. Beswick +10

Core-collapse SNe (CCSNe): Systematic searches of radio emission from CCSNe are still lacking, and only targeted searches of radio emission from just some of the optically discover…

Limit to the radio emission from a putative central compact source in SN1993J

I. Marti-Vidal, J. M. Marcaide

SN1993J in M81 is the best studied young radio-luminous supernova in the Northern Hemisphere. We recently reported results from the analysis of a complete set of VLBI observations…

Jet precession in the active nucleus of M81. Ongoing VLBI monitoring

I. Marti-Vidal, J. M. Marcaide, A. Alberdi +1

In a recent publication, we reported results of a multi-frequency VLBI campaign of observations of the Active Galactic Nucleus (AGN) in galaxy M\,81, phase-referenced to the supern…

VLBI observations of SN2011dh: imaging of the youngest radio supernova

I. Marti-Vidal, V. Tudose, Z. Paragi +11

We report on the VLBI detection of supernova SN2011dh at 22GHz using a subset of the EVN array. The observations took place 14 days after the discovery of the supernova, thus resul…

Detection of jet precession in the active nucleus of M81

I. Marti-Vidal, J. M. Marcaide, A. Alberdi +3

(See the complete and formatted abstract in the paper). We report on VLBI monitoring of the low-luminosity AGN (LLAGN) in M81 at 1.7, 2.3, 5, and 8.4GHz. These observations are pha…

Radio emission of SN1993J. The complete picture: II. Simultaneous fit of expansion and radio light curves

I. Marti-Vidal, J. M. Marcaide, A. Alberdi +3

We report on a simultaneous modelling of the expansion and radio light curves of SN1993J. We have developed a simulation code capable of generating synthetic expansion and radio li…

1.6 GHz VLBI Observations of SN 1979C: almost-free expansion

J. M. Marcaide, I. Marti-Vidal, M. A. Perez-Torres +4

We report on 1.6 GHz Very-Long-Baseline-Interferometry (VLBI) observations of supernova SN 1979C made on 18 November 2002. We derive a model-dependent supernova size. We also prese…

A Decade of SN1993J: Discovery of Wavelength Effects in the Expansion Rate

J. M. Marcaide, I. Marti-Vidal, A. Alberdi +15

We have studied the growth of the shell-like radio structure of supernova SN1993J in M81 from September 1993 through October 2003 with very-long-baseline interferometry (VLBI) obse…

Radio Supernovae: Circum-Stellar Investigation (C.S.I.) of Supernova Progenitor Stars

Christopher J. Stockdale, Kurt W. Weiler, Nino Panagia +8

Prior to explosion, a supernova progenitor slowly loses significant amounts of its hydrogen envelope in a stellar wind. After the explosion, the blastwave interacts with this wind…
